Question

我最近安装了django和psycop2。但是python拒绝在下面使用它是错误。有人可以帮忙吗？

>>> import psycopg2
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/psycopg2/__init__.py", line 67, in <module>
from psycopg2._psycopg import BINARY, NUMBER, STRING, DATETIME, ROWID

macports对于python / django开发来说很糟糕，一切似乎都没有数据。

我让我的团队为postgres做了以下事情：

下载并安装postgresql 9.0，但请先阅读README 安装!!!
从http://initd.org/pub/software/psycopg/
编辑setup.cfg以将pg_config设置为 /Library/PostgreSQL/9.0/bin/pg_config

然后用

python setup.py install

我建议您使用virtualenv，您希望尽可能远离基本的Mac OS X python安装。
